Cassette type liquid extracting device applied to low-temperature sterilization equipment

Abstract

The invention provides a cassette type liquid extracting device applied to low-temperature sterilization equipment. The cassette type liquid extracting device is characterized in that a needle base (7) equipped with a liquid extracting needle is fixedly connected with a substrate (1); a sliding plate (2) is parallel to the substrate (1) and is connected with the substrate (1) through a first sliding rail (11) which extends along the straight line in a sliding manner; the sliding plate (2) is also connected with a movable base (4) through a second sliding rail which is perpendicular to the first sliding rail (11); the movable base (4) is provided with a slot which extends along the direction being parallel to the first sliding rail (11); and a plate-strip shaped cassette (5) is positioned in the slot, and the wide edge of the cassette (5) is perpendicular to the sliding plate (2). The cassette type liquid extracting device provided by the invention has a simple structure and a smaller occupied space; miniaturization of the overall sterilization equipment is facilitated; and moreover, the cassette type liquid extracting device has the advantages that the cassette is convenient to replace and mount, a smaller operation window can only be reserved on a shell of the sterilization equipment, so that a good dust protection effect on the inner part of the equipment can be facilitated.

Description

technical field [0001] The invention relates to the technical field of low-temperature sterilization equipment, in particular to a cartridge-type liquid-taking device used for low-temperature sterilization equipment. Background technique [0002] In the medical field, the disinfection and sterilization of medical devices is particularly important. The sterilization methods mainly include high-temperature sterilization and low-temperature sterilization. Medical devices that are sensitive to moisture and heat mainly use low-temperature sterilization methods, such as those containing polymer materials, plastic materials, etc. Medical devices that are not resistant to high temperatures. [0003] A common low-temperature sterilization equipment is a hydrogen peroxide plasma sterilizer. When in use, hydrogen peroxide needs to be injected into the sterilization chamber of the equipment as a sterilizing agent. The injection methods mainly include bottled injection and cassette type....

AI Technical Summary

Problems solved by technology

[0003] A common low-temperature sterilization equipment is a hydrogen peroxide plasma sterilizer. When in use, hydrogen peroxide needs to be injected into the sterilization chamber of the equipment as a sterilizing agent. The injection methods mainly include bottled injection and cassette type. There are two types of injection, among which the bottled injection has been gradually eliminated due to the disadvantages of inaccurate liquid injection and other disadvantages. The current devices used for cassette injection generally have the following shortcomings: the device structure is complex and takes up a lot of space, which eventually leads to bulky sterilization equipment. Moreover, due to the inconvenience of changing the cassette, it is usually necessary to reserve a large operating window on the housing of the sterilization device, which will adversely affect the dust protection inside the device
